Okay, so I thought of giving a character with a Device like the Ivlivs from the Heroes of Olympus series. Basically, depending on what side the coin lands, a different weapon appears. I've already figured that I'd use Weapon Summoning (with the other weapon as an Alternate Power). The question is: How could I go about doing the "randomness" of the coin toss? Any suggestions?

I've only got two weapons (a flail and a shield [not a thrower like Steve Rogers']). After discussing it with my friends, I just decided to go with a regular coin-toss to decide. Since the character is a slightly toned-down version Marvel's Hercules, this seemed the way to go.

Find something to believe in. And find it for yourself. And when you do, pass it on to the future. - Iroquois Pliskin
